I know its not the best but is it worth the money ? its going in a 2003 4.8 silverado.

 

Yes in my opinion I would say it is worth it. I ended up putting down 640 to the wheels on e85 through an 80e. Just remember when you make a budget for the build, budget more, and then budget some more because this build nickel and dimed me to death.

 

On a 4.8 build I agree worth every penny. Allows for a lot of power on a budget, but prepare to spend a lot more on supporting parts.

 

So not just the $ for kit, but for fuel pump, injectors and built Trans?
Been eyeing this kit as well.

 

Supporting parts will depend if you have stock return or returnless. Also depends on desired power level. Big fuel pump like a Walbro 450 will require an aftermarket fuel regulator.

 

Right now I have a set of z06 injectors

I bought an Efan since IMA need it all I need is the fuel pump ? Any other besides the regulator you recommend me geetting
